ATTOR N EY Patented May 10, 1932 warren STATES JESSE R. ROYER, or JANnsvILLniown V ADJUSTABLE GAUGE AND STOP FOR GRADER BLADES Application filed May 5, 1930. Serial no. 449,905.

My invention relates to improvements in road graders, and the object of my improvements is to combine with a grader blade for both ends thereof, like devices for gauging the depth of cut by the blade and also serving as stops therefor adapted to ride upon the This object I have achieved by, the means v which are hereinafter described and claimed and which are illustrated in the accompanying drawings, in which Fig. 1 is an end elevation of a grader blade and of the adjustable depth gauge and stop mounted thereon. Fig.

90 2 is a fragmentary rear elevation of the grader blade, showing one end part thereof with said gauge and stop device in place thereon. Fig. 3 is a top plan of one of the gauge and stop plates of the device as mounted on a slide-shoe, and as detached from the connections to the grader blade.

It is to be understood that while but one device is shown as mounted on one end part of the grader blade, yet a like device is also to be similarly mounted on the opposite end part of the blade, giving like support thereto throughout.

It is also to be understood that various minor modifications may be effected in the said device without thereby departing from the principles of this invention or from the protection of the appended claim.

A grading device, or road maintainer machine, having a grader blade 1 longitudinally concaved or otherwise shaped, is liable when in movement and in operation over a soil surface, to tilt its frame and blade supports thereon in such a manner while upon rough ground or traversing hollows, so that either end of the blade will dig into the ground beyond the desired even depth, and my devices are intended to keep the blade in its proper position relative to the general ground surface, and to out therein evenly.

I have not shown the general grader construction because this is well known to those who areskilled in the art to which this invention appertains. In said Fig. 1 one end of a forwardly concaved or troughed blade 1 is shown, and having a removable reversible cutter plate 2 attached to depend therefrom, and secured by means of bolts 4. Angle-bars 5 and 3respectively are secured along the upper and lower parts of the rear face of the blade part 1 by means of bolts 6 and said bolts l. An angle-plate 7 is pivotally mount ed on a pivot-bolt 8 on the angle-bar 3. To its upright flange member is connected a hanger or link 10 which has a slot 25 traversed by a pivot-bolt 9.

A slide-shoe plate 15 is positioned inasubstantially horizontal position to the rear of the blade devices 1 and 2 to normally rest upon the ground surface at a desired gaged relation to the blade to thus limit the cut of the blade below the slide. Upon the slide 15' another plate 13 is secured by bolts 14 and has a medial forward apertured lug 12 and a number of transversely alined apert-ured lugs along the rear. The lower end of the hanger or link 10 has a pivotal connection 11 with the forward lug 12. An apertured lug or angle plate 19 is pivotally mounted upon the upper angle-bar 5 on a pivot-bolt 20. A sleeve 28 contains a rod 18, with a set-screw 24 for securing the sleeve in adjustment longitudinally on the rod. The sleeve has a forwardly projecting apertured lug 22 pivoted at 21 to said pivoted or swiveled lug or link 19. The lower end of the rod 18 is apertured and pivoted at 17 to one of the rear lugs 16 on the plate 13.

The universal joints at 8, 25 and 21 permit lateral adjustments of the jointed connections to any lug 16 ontheslideshoe 13 and 15, and

the pivot joint at 9 allows some swinging adjustments of the slide shoe 15. The sleeve 23 receives adjustably the rod 18, and the latter and the hanger 10 have pivotal connections to the slide-shoe 13 and 15, so that universal adjustments of the slide-shoe may be made relatively to the blade, and theconnect-ions fastened in their adjusted positions, permitting considerable adjustments to the shoe to conform it to required tilting of the blade on its supporting hangers not shown. Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

6 In combination with a grader blade and a slide-shoe, a link pivotally connected to the forward part of said slide-shoe and adj ustably connected with the lower part of the grader blade, alug connected to the upper 10 part of said grader blade for universal movement and having a sleeve thereon,- and a rod having its upper end adjust-ably mounted in said sleeve and having its lower end pivotally. secured to the rear of said slide-shoe. 15 In testimony whereof I ai'fix my signature.
